just my 2 cents

i think 4 hours of heating is a bit too long, no technical backup for it but my own exp

and last time i checked weed smelled and tasted like weed, generally the taste is not too pleasant to most ppl

and no matter what u do, using only weed, butter and water, there is no way to get rid of the taste. now i dont know how a vaped mj will taste but i can tell it should be along the same lines as dry non-vaped mj a lil worse perhaps

I have figured most ppl are too sassy about the taste. it all depends on what is the intent in cooking. i personally have come to ignore the taste and go for the better cause!

best brownies i have had, had chopped weed mixed in and they did taste like weed

however vaped weed has lost a good portion of its thc content as u can imagine
